Solutions of two electrolytes A and B are diluted. The `Lambda_(m)` of 'B' increases 1.5 times while that of A increases 25 times. Which of the two is a strong electrolyte? Justify your answer.

Explanation

To determine which of the two electrolytes, A or B, is a strong electrolyte, we can analyze the changes in their molar conductivity (λm) upon dilution.

### Step-by-Step Solution:

1. **Understanding Molar Conductivity (λm)**:
Molar conductivity (λm) is a measure of how well an electrolyte conducts electricity when dissolved in a solution. It is defined as the conductivity of the solution divided by the molar concentration of the electrolyte.

2. **Effect of Dilution on Strong and Weak Electrolytes**:
